Many people in Peoria Heights, Illinois who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. In fact, as many as 1/3 of those who struggle with mental health issues in Peoria Heights also take part in substance abuse at some time in their lives. These dual diagnosis clients typically turn to alcohol or drugs to self medicate as a way to relieve the symptoms of an underlying psychiatric issue. Some addicts aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehabilitation program is this sort of issue uncovered. This alone can help resolve addiction issues and put the person in a position to receive rehabilitation for both conditions so that they have a good chance of remaining clean and sober and mentally healthy in the future.
